R: Correlation of Community Centrality with Classic Centrality

corLinkcommCentrality {linkcomm} | R Documentation

## Correlation of Community Centrality with Classic Centrality

### Description

This function calculates the correlation between the community centrality and classic centrality measures for a set of nodes in a network, and plots a scatterplot of the relationship together with a fitted straight line.

### Usage

    corLinkcommCentrality(x, centrality = "degree", type = "commweight",
                          method = "spearman", plot = TRUE, pch = 20, ...)

### Arguments

`x` | An object of class `linkcomm`.
`centrality` | A character string naming the classic centrality measure. Can be one of `"degree"`, `"betweenness"`, `"closeness"`, and `"constraint"`. Defaults to `"degree"`.
`type` | A character string naming the type of community centrality. Can be `"commweight"` or `"commconn"`, defaults to `"commweight"`.
`method` | A character string naming the correlation method. Can be one of `"spearman"`, `"pearson"`, or `"kendall"`. Defaults to `"spearman"`.
`plot` | Logical, whether to plot a scatterplot of the relationship, defaults to TRUE.
`pch` | An integer specifying the plot symbol (see `par`). Defaults to 20.
`...` | Additional arguments to be passed to `plot`.

### Details

The correlation between community centrality and classic centrality measures, such as degree or betweenness, may reveal discrepancies, thereby indicating that community centrality scores provide a unique reflection of node importance.

### Value

A correlation coefficient.
